Description
A water-cooled structure for a silk spinning machine Technical Field
[0001] This utility model belongs to the field of silk spinning machine technology, and in particular relates to a water-cooling structure for a silk spinning machine. Background Technology
[0002] The high-speed wire rod rolling equipment includes a coiler. One type of coiler is horizontally arranged, tilted downwards at 20°, and consists of a coiling tube on a rotating hollow shaft and a transmission device. The rotating hollow shaft is driven by a motor via a pair of bevel gears. The coiling tube rotates at a set speed, thus producing coils with the required outer diameter. Its function is to use circular motion to coil the wire fed by the pinch rollers into circular coils. After passing through the coiling tube and guide plates, the wire finally falls onto the air-cooled roller conveyor for further cooling of the coils.
[0003] Because the wire enters the spinning machine at excessively high temperatures (generally above 800℃), the wear-resistant ring on the protective cover is constantly exposed to high temperatures. This can cause the wear-resistant ring to expand and deform due to heat. Although the deformation may not be severe, it poses a significant safety hazard for the spun wire. The main reason is that the spinning head of the spinning machine is located inside the guide plate, while the wear-resistant ring of the spinning machine's protective cover is located outside the guide plate. The gap between the wear-resistant ring and the guide plate (standard is generally around 2.5mm) must not be too large or too small. If it is too large (greater than 3mm), the wire will leak out through the gap, causing a steel pile-up accident. If it is too small, the wear-resistant ring will rub against the guide plate, damaging the equipment. Since wear-resistant rings are expensive, even domestically produced parts cost around 40,000 to 50,000 yuan, and imported parts are even more expensive. Therefore, measures should be taken to address the problem of thermal expansion of the wear-resistant ring and extend its online service life. Summary of the Invention
[0004] The purpose of this invention is to provide a water-cooling structure for a spinning machine to solve the problem that the wear-resistant ring on the protective cover of the spinning machine is subjected to high temperatures for extended periods, which can cause the wear-resistant ring to expand and deform due to heat. The technical solution adopted by this invention is as follows:
[0005] A water-cooled structure for a spinning machine includes an inner arc plate, an outer arc plate, a fan-shaped ring plate, and side plates. Both the inner and outer arc plates are arc-shaped plates with an upward convex center. The inner and outer arc plates are coaxially arranged. The front edge of the inner arc plate and the front edge of the outer arc plate are connected by the fan-shaped ring plate, and the rear edge of the inner arc plate and the rear edge of the outer arc plate are connected by another fan-shaped ring plate. The inner arc plate, the outer arc plate, and the two fan-shaped ring plates together form an arc-shaped cooling channel. The two side plates respectively close the two ends of the cooling channel. A water inlet pipe is provided in the middle of the outer arc plate, and a water outlet pipe is provided on both side plates. The outer surface of the inner arc plate is adapted to fit the upper surface of the wear-resistant ring of the spinning machine's protective cover.
[0006] Furthermore, the outlet pipe is a one-inch seamless pipe.
[0007] Furthermore, the inlet pipe is a two-inch seamless pipe.
[0008] Furthermore, the radius of the inner arc plate is 650mm.
[0009] Furthermore, the radius of the outer arc plate is 800mm.
[0010] Furthermore, several baffles are installed between the inlet pipe and the outlet pipe.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] The inner arc plate of this invention fits snugly against the wear-resistant ring. Cooling water is introduced through an inlet pipe and discharged through two outlet pipes. The cooling water flows through the cooling channel to cool the wear-resistant ring, thereby eliminating the risk of deformation caused by thermal expansion. This invention has a simple structure, requires little investment, and is quick to produce results, reliably solving the problem. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0020] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as bolt connections, snap-fit connections, pin connections, and hinge connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can be found to achieve this function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for a fixed connection, and a bolted connection can be chosen for a detachable connection.
[0021] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0022] Example: As shown in Figures 1 to 5, a water-cooled structure for a spinning machine includes an inner arc plate 1, an outer arc plate 3, a fan-shaped ring plate 2, and side plates 4. Both the inner arc plate 1 and the outer arc plate 3 are arc-shaped plates with an upward convex center. The inner arc plate 1 and the outer arc plate 3 are coaxially arranged. The front edge of the inner arc plate 1 and the front edge of the outer arc plate 3 are connected by the fan-shaped ring plate 2. The rear edge of the inner arc plate 1 and the rear edge of the outer arc plate 3 are connected by another fan-shaped ring plate 2. The inner arc plate 1, the outer arc plate 3, and the two fan-shaped ring plates 2 together form an arc-shaped cooling channel. The two side plates 4 respectively close the two ends of the cooling channel. The inner arc plate 1, the outer arc plate 3, the fan-shaped ring plate 2, and the side plates 4 form a closed hollow cooling shell. A water inlet pipe 5 is provided in the middle of the outer arc plate 3. A water outlet pipe 6 is provided on each of the two side plates 4. The outer surface of the inner arc plate 1 is adapted to fit the upper surface of the wear-resistant ring 8 of the spinning machine protective cover.
[0023] The high-speed wire rod rolling equipment includes a wire spinneret. One type of wire spinneret is horizontally arranged, tilted downwards at 20°, and consists of a spinning tube on a rotating hollow shaft and a transmission device. The rotating hollow shaft is driven by a motor via a pair of bevel gears. The spinning tube rotates at a set speed, thus producing coils with the required outer diameter. Its function is to spin the wire fed by the pinch rollers into circular coils using circular motion. After passing through the spinning tube and guide plate 9, the wire finally falls onto the air-cooled roller conveyor for further cooling of the coils.
[0024] Because the wire enters the spinning machine at excessively high temperatures (generally above 800℃), the wear-resistant ring 8 on the protective cover is constantly exposed to high temperatures. This can cause the wear-resistant ring 8 to expand and deform due to heat. Although the deformation may not be severe, it poses a significant safety hazard for the spinning wire. The main reason is that the spinning head of the spinning machine is located inside the guide plate 9, while the wear-resistant ring 8 of the spinning machine's protective cover is located on the outside of the guide plate 9. The gap between the wear-resistant ring 8 and the guide plate 9 (standard is generally around 2.5mm) must not be too large or too small. If it is too large (greater than 3mm), the wire will leak out of the gap, causing a steel pile-up accident. If it is too small, the wear-resistant ring 8 will rub against the guide plate 9, damaging the equipment. Since the wear-resistant ring 8 is expensive, even domestically produced parts cost around 40,000 to 50,000 yuan, and imported parts are even more expensive. Therefore, measures should be taken to address the problem of thermal expansion of the wear-resistant ring 8 and extend its online service life.
[0025] In this invention, the inner arc plate 1 is fitted and conforms to the wear-resistant ring 8. Cooling water is introduced through the inlet pipe 5 and discharged through two outlet pipes 6. The cooling water flows through the cooling channel to cool the wear-resistant ring 8, thereby eliminating the potential for deformation caused by thermal expansion. This invention has a simple structure, requires little investment, and is quick to produce results, reliably solving the problem.
[0026] The water outlet pipe 6 is a one-inch seamless pipe.
[0027] The inlet pipe 5 is a two-inch seamless pipe. The cross-sectional area of the inlet pipe 5 is larger than that of the two outlet pipes 6, which makes it easy to fill the cooling channel with cooling water.
[0028] The radius of the inner arc plate 1 is 650mm to fit the wear-resistant ring 8 of the wire spinning machine.
[0029] The outer arc plate 3 has a radius of 800mm, and the outer arc plate 3 is spaced 150mm apart from the inner arc plate 1 to form a cooling channel of appropriate thickness.
[0030] Several baffles 7 are installed between the inlet pipe 5 and the outlet pipe 6. The baffles 7 divide the cooling channel into a serpentine shape, so that the cooling water can fully exert its cooling effect before flowing out of the cooling channel. The inner arc plate 1, the outer arc plate 3, the fan ring plate 2, the side plate 4, the inlet pipe 5, the outlet pipe 6, and the several baffles 7 constitute a water cooling device.
[0031] The above embodiments are merely illustrative examples of the present utility model and do not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present utility model, they are all within the scope of protection of the present utility model.
